How Mila Kunis Tamed Bad Boy Ashton Kutcher: ‘Non-Stop Sex!’ Says Source

Ashton Kutcher and Mila Kunis were once considered to be two of the wildest members of young Hollywood, but a source close to the couple tells RadarOnline.com exclusively that Mila has certainly tamed her bad boy fiancé and father-to-be — and vice-versa. With a daughter on the way, Kutcher would rather be at home with Mila than out on the Hollywood scene, and there seems to be good reason.

“They have non-stop sex!” an insider tells Radar. “Mila is insatiable in bed and they cannot get enough of each other. Ashton thinks she is the sexiest woman he has ever met.”

For that and other reasons, “They really just love staying at home,” the source says. "Mila loves to cook dinner for them almost every night and she is a really great cook.”

“They are both very health-conscious people.” the source continues. "Being pregnant, Mila must be — and Ashton has really changed as well. He rarely ever drinks and they are both very against drugs.”

But even with a baby on the way, Mila, 30, and Ashton, 36, have already welcomed a new addition: “Ashton bought Mila the cutest little black puppy ever,” the source says. “They named him Bernie.”
